一维Luttinger模型的精确Jastrow-Slater波函数

Exact Jastrow-Slater wave function for the one-dimensional Luttinger model

Benjamin Tayo, Sandro Sorella

摘要:

我们表明,它是可能的描述的Luttinger模型的基态的Jastrow-Slater波函数。此外,我们的研究结果表明,一个粒子的激发和它们相应的动态可以忠实地表示只有当一个类似形式的杰斯特罗因子被应用到一个连贯的叠加许多斯莱特行列式。我们讨论了可能的相关性,这种方法的理论描述的光电子能谱在更高的维度,本波函数可以简单地概括,并可以用作变分分析,这是准确的1D Luttinger模型。

英文摘要:

We show that it is possible to describe the ground state of the Luttinger model in terms of a Jastrow-Slater wave function. Moreover, our findings reveal that one-particle excitations and their corresponding dynamics can be faithfully represented only when a Jastrow factor of a similar form is applied to a coherent superposition of many Slater determinants. We discuss the possible relevance of this approach for the theoretical description of photoemission spectra in higher dimensionality, where the present wave function can be straightforwardly generalized and can be used as a variational ansatz, that is exact for the 1D Luttinger model.
